Convertible Program (E64 Only)

WARNING: This page does not describe the selected car, but rather 33 other vehicles, including the 2010 BMW M5, 2009 BMW M5, 2008 BMW M5, 2008 BMW 760Li, and 2007 BMW M5. However, it is still accessible from the selected car via links, so may be relevant.

The convertible program is activated in the factory, (this factory setting can be deactivated win the Car and Key Memory). Switch-on conditions:

Terminal 15 ON
Convertible top open

The convertible program comprises the following functions:

The condensation sensor is switched off
The blower speed increases with increasing road speed
Air distribution is switched to the upper body and head, airflow to the footwell is throttled
Dynamic pressure compensation is changed, i.e. as road speed increases, the volume of air fed into the vehicle through the fresh air grille increases.
Solar sensor control variables are changed
When the convertible top is open, the solar sensor evaluates the surrounding brightness (darkness to intense sunshine) more strongly. For this reason, the solar sensor has a stronger effect on the IHKA controls when the convertible top is open.

In the convertible program, the blower speed can be changed manually at the IHKA controls. The automatic flap control remains active (no change to flap position). If the convertible program is active and the flap positions are changed with the CID and controller, the convertible program will be deactivated. This means that manual settings will be assumed, unchanged settings will revert to those that the air-conditioning system had before the convertible top was closed.

The convertible program can be completely reactivated by pressing the AUTO button.
